How can you succeed as a startup

We at Mashauri greatly admire Y Combinator (the San Francisco based accelerator - and in fact the first ever accelerator). They began a Startup School a few years ago and I would like to share this video from Sam recorded in 2017 where he talks about how you can succeed as a startup. We are adding it in here for our Ashoka students - but is valuable for anyone in this field be it entrepreneur or educator.
